Multiferroics are novel systems that display simultaneous magnetic and polar ordering. These systems have recently stimulated much scientific and technological interest because of the coexistence of magnetic and polar subsystems. However, single-phase materials that exhibit the coexistence of strong ferro/ferrimagnetism and ferroelectricity are scarce. Perovskite-type BiFeO3, hexagonal REMnO3 (RE=rare earths), and rare earth molybdates are among the few single-phase multiferroics. The drawback of these materials is the weak spin-lattice coupling under moderate conditions, which certainly limits their applicability in devices. Various approaches have been proposed to circumvent this hurdle. Among these, composites consisting of ferroelectric/piezoelectric and magnetostrictive phases can be electromagnetically coupled via stress mediation. In a film-on-substrate geometry, these composites can be obtained as vertically-aligned structures grown on crystalline substrates. This approach is general, and the artificial superlattices are expected to exhibit a strong coupling of the order parameters through the heteroepitaxy of the two lattices, which can lead to completely new phenomena or improved properties of the parent components. The fact that artificial vertical superlattices feature a larger interfacial surface area and are intrinsically heteroepitaxial in three dimensions, favors the stronger coupling between ferroelectric and magnetic components. Hence, the coupling in vertically arranged superlattices takes place through vertical heteroepitaxy. In this regard, measurements on artificially engineered multiferroics such as those comprising ferro- or piezoelectrics and carrier-mediated magnets such as manganite have shown that the coupling can proceed through an electric field effect at the interface . Here, the ferroelectric material influences the magnetic behavior of the heterostructure by modulating the carrier density in the magnetic layer via a conventional electric field effect. This is a promising result, which should also be explored in other artificial heterostructures. In the present investigation, the versatility of deposition systems such as the pulsed-laser ablation technique (PLD) and/or sputtering for fabricating superlattices composed of a multiferroic (TbMnO3) and a paralectric/ferroelectric (SrTiO3) will be exploited. The [(TbMnO3)m(SrTiO3)m]x (m=1 to 10 unit cells; x=15-20) superlattices grown on (001)-oriented SrTiO3 substrates by means of pulsed laser deposition y/or sputtering will be characterized by using various techniques according to their structural, magnetic, electric, and ferroelectrical properties. The structural properties will be studied by means of X-ray diffractometry and X-ray photoelectron spectroscopy. The magnetic properties in turn will be determined by SQUID magnetometry. The electric transport will be analyzed by evaluating the dependence of the resistivity on the temperature. The dielectric properties will be assessed by complex impedance spectroscopy. Finally, the ferroelectric behavior of the heterostructure as well as the possible magnetoelectric coupling will be investigated by polarization measurements in the presence of a magnetic field. Here, it should be mentioned that Raman spectroscopy is also a suitable technique to evaluating the ferroelectric properties of a material both in bulk or thin film form. It is expected that the multiferroic properties of the superlattices to depend on the paraelectric/ferroelectric behavior of the SrTiO3 layers, as well as on the periodicity of the heterostructure. A probable dependence of the ferroelectricity in SrTiO3 layers on the multiferroism of the superlattice is also expected. In general, a stronger multiferroic coupling is expected to occur in (TbMnO3)m(/SrTiO3)m superlattices.
